wcf callback slow server response

Can someone please give me a hint what is the main module in wcf callback (notification) which affects fastness and slowness of the broadcast response in client.

Here, the code used net.tcp. if ever my question i开发者_开发问答s not that clear please let me know. I surely missed something.

The timeout, or amount of time that WCF will wait for a response from the service before throwing a TimeoutException, is controlled via the service binding configuration.
